Question

Label the conjugate acid base pairs in each equation

Answer 1

Answer:

In acid-base reactions, the acid donates a proton and the species that is left is its conjugate base. The base accepts a proton and the species formed is the conjugate acid.

For a)

HF loses a proton to H2O. HF becomes F- and H2O becomes H3O+

HF is the acid and its conjugate base is F-

H2O is the base and its conjugate acid is H3O+

I am focusing on the forward reactions in my explanation; notice that in the reverse reaction, the conjugate base acts as the base and the conjugate acid acts as the acid.

*the pairs are HF / F- and H2O/H3O+

For b)

HNO3 loses a proton and becomes NO3-

OH- accepts a proton and becomes H2O

HNO3 is the acid and its conjugate base is NO3-

OH- is the base and its conjugate acid is H2O

*the pairs are HNO3 / NO3- and OH-/H2O
